INTRODUCTION
This concrete vibrator motor is used to power concrete flex
shaft vibrators which provide vibration to consolidate freshly
poured concrete The vibration is created by an eccentric (off
center) weight within the vibrator head As the weight spins
it forces the head housing to move within the fresh concrete
The continuous head movement agitates the concrete
mixture resulting in significantly reduced voids
This motor can be used with any valid Wyco vibrator head
and shaft combination See
for recommended
combinations Shafts are available in lengths of 2, 5, 7, 10, 14,
20 and 30 feet (0 61, 1 52, 2 13, 3 05, 4 27, 6 1 and 9 14 m)

Before Starting the Motor
DO NOT USE DAMAGED EQUIPMENT. INSPECT
THE VIBRATOR FOR DAMAGE BEFORE USING THIS
EQUIPMENT. READ, UNDERSTAND AND FOLLOW ALL
SAFETY AND MAINTENANCE INSTRUCTIONS IN THIS
MANUAL. CAREFULLY CHECK THAT THE POWER CORD
HAS NO CUTS OR EXPOSED WIRES. VERIFY MOTOR
HOUSING IS INTACT. CHECK ALL ACORN NUTS TO VERIFY
THEY ARE TIGHTENED.
DO NOT START THE MOTOR WITHOUT A SHAFT
CONNECTED. THE EXPOSED SHAFT CONNECTION
PRESENTS A SAFETY HAZARD AS IT ROTATES AT HIGH
SPEED. CLOTHING OR SKIN MAY BECOME ENTANGLED IN
THE SHAFT CONNECTION CAUSING INJURY.
Make sure that the motor, shaft and head are connected
securely See
Make sure that the power plug is connected to the
appropriate power source
Make sure that the motor is not immersed in concrete and
that any cord connections are not in water or fresh concrete

The SureSpeed has been designed with a soft start
and will ramp up to speed over a 1 second period
2 Insert the vibrator head into the concrete to be
consolidated
Do not run the vibrator head outside of fresh concrete
for an extended period of time The vibrator depends on
moving concrete to cool the bearings
Avoid sharp bends in the flex shaft during operation
Sharp bends reduce shaft life
